when iterating, it always needs to initialize the left factor to 0?

[jackyhawk]

As for als ,

when iterating, it always needs to initialize the left factor to 0?

what if I just use setFactors(genUnif) to initialize the left factor in the first round of optimizing,
and then just keep the fitting factors in later iterating?

---

And what if i change the als training as the incremental mini-batch mode, shall i still need to initialize the left factor to 0?

Thanks very much

Shall I just load the left factor from other iteration (or mini-batch) result,

and comment these two lines?

#if 0
auto genZero = { return 0.0; };
leftData.setFactors(genZero);
#endif
